Sensitivity level determination block
ISO 3452-1 Type 1 Test Panel
Detection sensitivity: Evaluate whether the penetrant can detect minor defects by detecting star shaped cracks on the test block.
Cleanability: By measuring the roughness area on the test block, determine the ease of cleaning the penetrant on the rough surface.
Structure and Parameters
Kit composition: A set of 4 brass plates with electroplating thicknesses of 10 μ m, 20 μ m, 30 μ m, and 50 μ m.
Regional division of labor: Each test block is divided into two parts:
Chrome plated area: There are 5 star shaped cracks used for sensitivity evaluation.
·Rough area: with a roughness of Ra 2.5 μ m to 15 μ m, used for washability measurement.
Applicable type:
10 μ m, 20 μ m, and 30 μ m test blocks: used for fluorescent penetrants.
30 μ m and 50 μ m test blocks: used for coloring penetrants.

Sensitivity* (unofficial) |
Fluorescent Penetrant Sensitivity Levels are established by the USAF Laboratory under highly controlled conditions. Sensitivity testing is not something the penetrant manufacturer or user can do. What you can do is compare samples using appropriate NiCr Cracked Panels. |
